Quick Answer
Real lawn costs £5–£15/m² to install (seed or turf), while artificial grass costs £20–£60/m² installed. Artificial grass needs minimal upkeep but has environmental downsides; real lawn is cheaper upfront and better for wildlife, but requires regular maintenance.
It's one of the most common debates in UK gardening in 2026: should you lay artificial grass or stick with a real lawn? Both options have genuine advantages, and the right choice depends on your lifestyle, budget, garden use, and environmental values. This guide gives you an honest, side-by-side comparison so you can make an informed decision.

Cost Comparison: Artificial vs Real Lawn
The upfront cost difference is significant, but it's only part of the picture. Real lawn looks cheaper on day one, but ongoing maintenance costs add up over years. Artificial grass costs more to install but removes most recurring expenses.
| Cost Factor | Real Lawn | Artificial Grass |
|---|---|---|
| Installation (per m²) | £5–£15 (turf) / £1–£4 (seed) | £20–£60 installed |
| 50m² lawn total install | £250–£750 (turf) | £1,000–£3,000 |
| Annual maintenance cost | £200–£600/yr (mowing, feed, weed) | £20–£50/yr (brushing, cleaning) |
| Irrigation (hot summers) | £50–£200/yr extra in drought | None |
| Repairs / patching | £20–£100 for reseeding bare patches | £100–£400 for professional repair |
| Replacement after lifespan | Reseed/re-turf every 10–20 yrs | Full replacement every 10–15 yrs |
| 10-year total cost (50m²) | ~£2,500–£7,000 | ~£2,000–£4,500 |
For larger gardens, real lawn wins on installation cost comfortably. But for small urban gardens of under 30m², the long-term costs can be surprisingly similar once you account for mowing, fertilising, scarifying, and watering.

Side-by-Side Comparison
| Factor | Real Lawn | Artificial Grass |
|---|---|---|
| Upfront cost | Lower | Higher |
| Weekly maintenance | High (mowing, edging) | Minimal |
| Appearance in hot summers | Can yellow/brown | Stays green year-round |
| Temperature in sun | Cool and comfortable | Gets very hot (up to 60°C+) |
| Pet use | Durable, self-repairs | Odour can build up |
| Children playing | Soft and natural | Hard base, no give |
| Wildlife value | High (insects, birds, soil life) | Very low |
| Drainage | Natural drainage | Requires permeable base |
| Planning restrictions | None | Some councils restrict it |
| Smell after rain | Fresh petrichor scent | None / plastic odour |
| Lifespan | Ongoing if maintained | 10–15 years before replacement |
| CO2 absorption | Yes (absorbs carbon) | None |
Maintenance Comparison
Real grass requires regular mowing throughout the growing season (March–October), typically every 1–2 weeks. It also benefits from annual scarification to remove thatch, aeration every few years, and seasonal feeding with the right fertiliser. A good gardener can handle all of this — read our guide on how to find a reliable gardener to make sure you choose well.
Artificial grass, by contrast, needs brushing with a stiff broom every month or two to keep fibres upright, occasional rinsing to remove dust and debris, and prompt cleaning of pet mess or organic matter to prevent odour. It won't need mowing, feeding, or watering — but it isn't truly maintenance-free.
Environmental Considerations
This is where real lawn has a clear advantage. Natural grass supports biodiversity — bees, beetles, worms, and birds all depend on lawn ecosystems. Grass also absorbs rainwater naturally, reducing surface run-off and flood risk, and absorbs CO2. Soil health improves under well-maintained turf.
Artificial grass is made from polypropylene — a plastic — and typically ends up in landfill at the end of its life. It prevents rainwater from soaking into the ground, can increase local surface temperatures significantly, and eliminates habitat for soil organisms. Some UK local councils have started discouraging or restricting its use for these reasons.
If you want a low-maintenance outdoor surface but care about the environment, you might also consider hard landscaping alternatives. Our guide on decking vs patio covers these options in detail, and patio installation costs are often comparable to artificial grass.
Lifespan and Longevity
A properly laid and maintained real lawn has no fixed lifespan — it can last indefinitely with the right care. Even neglected lawns can be restored with overseeding and scarification. Real grass regenerates naturally.
Artificial grass typically lasts 10–15 years before fibres start to flatten, fade, or deteriorate. Budget products may need replacing in as little as 7–8 years. Premium grades with UV stabilisation and high pile weight can last closer to 20 years. At end of life, the entire installation — including the rubber crumb infill — needs removing and disposal.
When Each Is the Right Choice
Choose artificial grass if…
- You have a small urban garden and genuinely cannot commit to regular mowing
- The garden gets very heavy foot traffic that real grass struggles to survive
- You have mobility issues that make garden maintenance difficult
- You are renting and a landlord wants a low-maintenance solution
- The area gets very little light and real grass won't grow well
Choose real lawn if…
- You have children who play on the grass regularly (softer landing, cooler in sun)
- You value the natural environment and want to support garden wildlife
- You have a larger garden where artificial grass costs become prohibitive
- You're thinking about long-term property value — real lawn is almost universally preferred by buyers
- You enjoy gardening as a hobby and find grass care satisfying
Frequently Asked Questions
Does artificial grass add value to a house?+
The evidence suggests artificial grass is neutral or slightly negative for property value in the UK. Many buyers and estate agents note it as a negative — particularly environmentally-conscious buyers and families with young children. Real lawn is almost always preferred by purchasers.
How hot does artificial grass get in summer?+
Artificial grass can reach 50–65°C on a sunny UK summer day — hot enough to cause discomfort and potential burns for children and pets. Real grass stays close to ambient temperature because moisture in the soil keeps it cool. This is a significant practical consideration for families.
Can I install artificial grass myself?+
DIY installation is possible for small, simple areas. However, getting the compacted sub-base right — typically 100mm of hardcore plus 25mm of sharp sand — is critical to prevent sinking and drainage problems. Poor installation voids most warranties. For anything over 20m², professional installation is recommended.
Is artificial grass safe for dogs?+
Artificial grass is generally safe for dogs, but urine can accumulate in the infill and cause persistent odour, especially in warm weather. Regular rinsing with water is essential. Some premium grass products include antimicrobial infill to address this. Real grass drains and cleans naturally after rainfall.
Do I need planning permission to lay artificial grass?+
In most cases, no. However, if you're in a conservation area, have a listed property, or are laying it over the front garden (which changes drainage), your local council may have restrictions. Some newer developments have covenants preventing artificial grass — always check your deeds.
What is the best quality artificial grass in the UK?+
Look for a pile height of 30–40mm, a pile weight of at least 2,500g/m², UV stabilisation, and a latex backing. Reputable UK suppliers include Namgrass, LazyLawn, and NeoGrass. Avoid very cheap products under £10/m² — they look and feel noticeably artificial and deteriorate quickly.
